Description

Technical Field

[0001] This invention relates to the technical field of anatomy teaching and experimental equipment, and in particular to an automated composite transmission mechanism for a teaching anatomy table. Background Technology

[0002] A teaching dissection table typically consists of a dissection workbench, sample containers, a ventilation system, a drainage system, and a sealing system. The sample containers contain a certain volume of formalin solution. During sample storage, the dissection workbench is lowered below the solution level, immersing the sample in the solution. The sealing cap on top of the container is closed to prevent formalin evaporation. Traditional dissection tables have the following technical drawbacks:

[0003] 1. Separation of storage and handling: Samples need to be soaked in solution during storage, and need to be manually removed or the platform manually raised during dissection. The operation is cumbersome and can easily cause the formalin solution to evaporate, which is harmful to the health of the operators.

[0004] 2. Independent control of sealing and lifting: The existing equipment has two independent systems for the lifting mechanism and the sealing cover opening and closing mechanism, which require step-by-step operation, resulting in low automation and the risk of solution evaporation and sample contamination due to untimely sealing;

[0005] 3. Complex structure and poor reliability: Some linkage mechanisms adopt multi-motor drive or complex transmission structure, which is costly, difficult to maintain, and prone to asynchronous movement and jamming failures;

[0006] Therefore, there is an urgent need for a dissection table with a simple structure that can be automated with one click to solve the above problems. Summary of the Invention

[0007] The main technical problem solved by this invention is to provide an automated composite transmission mechanism for a teaching dissection table, which realizes the synchronous linkage between the lifting and lowering of the dissection worktable and the opening and closing of the roller shutter sealing cover, and completes the switching between sample storage and dissection operation states with one click. At the same time, it improves the sealing performance, reliability and ease of operation of the equipment, and reduces the safety hazards caused by the volatilization of formalin solution.

[0008] To solve the above-mentioned technical problems, one technical solution adopted by the present invention is: to provide an automated composite transmission mechanism for a teaching dissection table, comprising:

[0009] A dissection table frame and a container disposed within the frame, the container being used to hold formalin solution;

[0010] The dissection worktable is located inside the container and can move up and down vertically.

[0011] The cross lifting assembly is connected to the lead screw and nut pair at the lower end and hinged to the dissection worktable at the upper end.

[0012] A lead screw includes a driving lead screw and a driven lead screw, wherein the driving lead screw and the driven lead screw are respectively provided with a lead screw thread section and the lead screw nut pair is fitted on the lead screw thread section;

[0013] The synchronous transmission assembly includes a driving synchronous pulley, a first driven synchronous pulley, a second synchronous pulley, a third synchronous pulley, and a synchronous belt arranged around the four sets of synchronous pulleys. The ends of the driving positive and negative lead screws and the driven positive and negative lead screws are connected by the driving synchronous pulley, the first driven synchronous pulley, and the synchronous belt to achieve synchronous rotation of the two lead screws.

[0014] A roller shutter sealing cover is installed at the top opening of the container. The roller shutter sealing cover is connected to the end of the synchronous belt and can be opened and closed with the movement of the synchronous belt.

[0015] A drive motor is connected to the end of the active positive and negative lead screw and is used to drive the active positive and negative lead screw to rotate in both directions.

[0016] In a preferred embodiment of the present invention, the cross lifting assembly is a scissor lift mechanism, consisting of two sets of cross-hinged connecting rods. The lower end of each set of connecting rods is respectively hinged to the lead screw and nut pair on the active and driven lead screws. The upper end of each set of connecting rods is provided with rollers and is rolledly connected to the roller conveyor on the dissection worktable to support the dissection worktable.

[0017] In a preferred embodiment of the present invention, when the drive motor drives the two sets of lead screws to move, thereby driving the two sets of lead screw nut pairs to move towards each other along the positive and negative thread sections, the cross lifting assembly is raised to drive the dissection worktable to move upward; when the lead screw nut pairs move in opposite directions, the cross lifting assembly is lowered to drive the dissection worktable to move downward.

[0018] In a preferred embodiment of the present invention, the synchronous belt and the roller shutter sealing cover are connected by a hinge. When the active positive and negative lead screws rotate, the synchronous belt drives the roller shutter sealing cover to open or close the top opening of the container synchronously.

[0019] In a preferred embodiment of the present invention, when the active and driven lead screws drive the dissection worktable to rise, the synchronous belt drives the roller shutter sealing cover to open synchronously; when the active and driven lead screws drive the dissection worktable to descend, the synchronous belt drives the roller shutter sealing cover to close synchronously.

[0020] In a preferred embodiment of the present invention, the container is a sealed cavity, and the top opening of the container is adapted to the roller shutter sealing cover. When the roller shutter sealing cover is closed, it can completely cover the top opening of the container.

[0021] In a preferred embodiment of the present invention, the roller shutter sealing cover is made of a corrosion-resistant flexible material and can completely cover the top opening of the container when closed.

[0022] In a preferred embodiment of the present invention, the active synchronous pulley is disposed on one end of the active positive and negative lead screw, the first driven synchronous pulley is disposed on one end of the driven positive and negative lead screw, and the second and third synchronous pulleys are respectively rotatably disposed on the top two ends of the dissection table frame. The active synchronous pulley, the first driven synchronous pulley, the second synchronous pulley and the third synchronous pulley are connected by the synchronous belt.

[0023] In a preferred embodiment of the present invention, the side wall of the container is provided with an observation window for observing the liquid level of the formalin solution and the state of the sample.

[0024] In a preferred embodiment of the present invention, a control unit is further included, which is electrically connected to the drive motor and is used to preset the lifting stroke and movement speed of the worktable.

[0025] The beneficial effects of this invention are: to realize the synchronous linkage between the lifting and lowering of the dissection worktable and the opening and closing of the roller shutter sealing cover, to complete the switching between sample storage and dissection operation states with one click, and at the same time improve the sealing performance, reliability and ease of operation of the equipment, and reduce the safety hazards caused by the volatilization of formalin solution. Attached Figure Description

[0026] To more clearly illustrate the technical solutions in the embodiments of the present invention, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention, wherein:

[0027] Figure 1 This is a schematic diagram of the structure of an automated composite transmission mechanism for a teaching dissection table according to the present invention. Detailed Implementation

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1 The present invention includes: an automated composite transmission mechanism for a teaching dissection table, comprising: a dissection table frame 1, a container 2, a dissection worktable 3, a cross lifting assembly 4, positive and negative lead screws, a synchronous transmission assembly, and a roller shutter sealing cover 5.

[0030] Furthermore, the dissection table frame and the container within the frame, the container being used to hold formalin solution, the dissection worktable being disposed within the container and capable of vertically lifting and lowering under the drive of the cross-lifting assembly, the cross-lifting assembly having its lower end connected to a lead screw and nut pair and its upper end hinged to the dissection worktable; the lead screws include a driving lead screw 6 and a driven lead screw 7, each with a corresponding threaded section 8, and the lead screw and nut pair 14 fitted onto the threaded sections; the synchronous transmission assembly includes a driving synchronous pulley 9 and a first driven synchronous pulley 10. The system includes a second synchronous pulley 11, a third synchronous pulley 12, and a synchronous belt 13 arranged around the four sets of synchronous pulleys. The driving synchronous pulley is located on one end of the driving positive and negative lead screw, and the first driven synchronous pulley is located on one end of the driven positive and negative lead screw. The second and third synchronous pulleys are respectively rotatably arranged on the top two ends of the dissection table frame. The four sets of synchronous pulleys are connected by the synchronous belt. The ends of the driving positive and negative lead screw and the driven positive and negative lead screw are connected by the driving synchronous pulley, the first driven synchronous pulley, and the synchronous belt to achieve synchronous rotation of the two lead screws.

[0031] Furthermore, a roller shutter sealing cover is located at the top opening of the container and is connected to the end of the synchronous belt. It can be opened and closed with the movement of the synchronous belt. The container is a sealed cavity, and the top opening of the container is adapted to the roller shutter sealing cover. When the roller shutter sealing cover is closed, it can completely cover the top opening of the container. Preferably, the roller shutter sealing cover is made of a corrosion-resistant flexible material. When closed, it can completely cover the top opening of the container. In the storage state, the dissection workbench is in the lowest position and is completely immersed in the formalin solution. When the roller shutter sealing cover is closed, it completely seals the top opening of the container, effectively preventing the formalin solution from evaporating and reducing health hazards to operators.

[0032] Furthermore, it also includes a drive motor (not shown in the figure), which is connected to the end of the active positive and negative lead screws to drive the active positive and negative lead screws to rotate in both directions. When the drive motor drives the two sets of lead screws to move, thereby driving the two sets of lead screw nut pairs to move towards each other along the positive and negative thread sections, the cross lifting assembly is raised to drive the dissection worktable to move upward. When the lead screw nut pairs move in opposite directions, the cross lifting assembly is lowered to drive the dissection worktable to move downward. The synchronous belt is hinged to the roller shutter sealing cover to realize the transmission connection. When the active positive and negative lead screws rotate, the synchronous belt drives the roller shutter sealing cover to open or close the top opening of the container synchronously.

[0033] Furthermore, the cross-lifting assembly is a scissor-type lifting mechanism, consisting of two sets of cross-hinged connecting rods. The lower end of each set of connecting rods is hinged to the screw-nut pair on the active and driven screws, respectively. The upper end of each set of connecting rods is equipped with rollers, which are rolled within the roller conveyor on the dissection worktable to support it. When the active and driven screws drive the dissection worktable to rise, the synchronous belt drives the roller shutter sealing cover to open synchronously. When the active and driven screws drive the dissection worktable to fall, the synchronous belt drives the roller shutter sealing cover to close synchronously. The drive motor rotates forward, and the active screws rotate, which in turn drives the driven screws to rotate synchronously via the synchronous belt. The screw-nut pair moves in opposite directions, pushing the cross-lifting assembly to rise, thus raising the dissection worktable. At the same time, the synchronous belt drives the roller shutter sealing cover to open synchronously. When the worktable reaches the set height, the sealing cover is fully open, allowing for dissection operations. The resetting action of the dissection worktable is the reverse, and will not be described in detail here.

[0034] In another embodiment of the present invention, an automated composite transmission mechanism for a teaching dissection table includes the above-mentioned lifting mechanism and sealing cover linkage mechanism of the dissection table, and also includes a control unit. The control unit is electrically connected to the drive motor and can preset the lifting stroke and movement speed of the worktable to achieve automated control. Preferably, a transparent observation window is provided on the side wall of the container to facilitate observation of the liquid level of the formalin solution and the sample status inside. The roller shutter sealing cover can be made of corrosion-resistant PVC flexible material, which is adapted to the top opening of the container and has a good sealing effect.

[0035] The beneficial effects of the automated composite transmission mechanism for a teaching dissection table of the present invention are:

[0036] (1) Synchronous linkage: Driven by the drive motor, the lifting of the dissection worktable and the opening and closing of the roller shutter sealing cover are synchronously linked, and the switching between storage and dissection status can be completed with one click without step-by-step operation, which greatly improves the convenience of operation.

[0037] (2) Sealed protection, safe and environmentally friendly: The roller shutter sealing cover moves synchronously with the workbench, and the container is completely sealed in the storage state, which effectively prevents the volatilization of formalin solution, reduces the health hazards to operators, and avoids sample contamination and solution leakage.

[0038] (3) Simple structure and high reliability: It adopts a single set of synchronous belt drive and positive and negative screw drive, without the need for multiple motors or complex control structure, with low failure rate and convenient maintenance, and is suitable for long-term stable use in teaching and experimental scenarios.

[0039] (4) Smooth lifting and strong adaptability: The scissor cross mechanism lifts smoothly and has a strong load-bearing capacity. It can be adapted to anatomical samples of different sizes to meet the needs of various anatomy teaching and training.

[0040] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
